Specification of Letters Patent.

:Patented March 23, 1909.

Application filed October 5, 1905. Serial No. 281,482.

To all whom it may concern:

Be it known that I, EDWARD REYNOLDS, of Milton, in the county of Norfolk and State of Massachusetts, a citizen of the United States, have invented a new and useful Improvement in Wrenches, of which the following is a full, clear, and exact description, re erence being had to the accom anying drawings, forming a part of this specilDi in explaining its nature.

The obj ect of my invention is to rovide a wrench having a head arranged w ereby it may be turned through a complete circle of rotative movement, which head has a slot cut therein and open from the side thereof whereby the head may engage a nut or other object to be turned when applied laterally thereto, and which head isoperated or turned by a series of short, intermittent or repeated strokes of a handle or lever with which the head connects and whereby the head may be turned and the wrench be used in a narrow or conned place.

It is a further object'of my invention to provide a wrench of the above'kind which shall be of superior Strength, easily operatable and of a simple construction, admitting of the wrench being manufactured and sold at a comparativley low cost.

My invention can best be seen and underi stood by reference to the drawings, in which- Figure 1 shows the wrench in side elevation, and Fig. 2 shows a cross section of the wrench on the line 2*2 of Fig.

In the drawings: A represents the head of the wrench. The head is made 4round in the form of a thick or wide disk and has cut into it on the side thereof a slot or opening a for receiving a nut or other object to be turned. The periphery or rounding edge of the head is serrated by teeth a1 by which the head isturned as will hereinafter be explained.

The head is arranged to turn in and between the sides of a casing B. t, t1 represent these sides, there being formed therein large annular bearin s b2 in which the head is adapted to turn by ubs a2 extending from. the sides thereof and iitting into these bearings. Thelsizeof the annular bearin js b2 are especially to be noted, these bearings ein in fact so large that the slot 'cut in the hea of the wrench will lie within the planes of the circle prescribed by the bearings so that a nut or other object litting within said slot may cation,

turn as the head is turned without interfering with the bearings.

In order that the head of the wrench may be appllied to a nut or other object the casing or rat er the sides of the casing are cut away in part forming an opening by which the nut may enter the slot cut in the head.

C represents the handle of the wrench or lever by which the head is turned. This lever is arranged to enter the casing B and extend alongside or by the head and is pivoted between the sidesb,l 1of the casing in which the head turns by a pin c. Thus arranged the lever is adapted to engage the head when turned down and the edge of the lever at the point of its engagement is made serrated by teeth c1 to insure an effective grip.

The lever having been brought into engagement with the head the operation of turning the head is effected by further turning of the vlever in the same direction when all the parts including the head will turn together as will also the nut or other object engaged by the head. After the lever has been turned a short distance the engagement edge thereof may be released from the head simply by turning the lever in a reverse direction. Thereupon and especially when the lever strikes the side or edge t3 of the casing connecting the sides thereof and on the other side of the lever away from the head, the casing will be made to turn or shift on the head, or in other words, will turn on the hubs of the head when the lever will be brought around to or shifted into a position where it may take a fresh grip on the toothed edge ofthe head and its further turning effected. In fact b y repeating this action the head and the nut or object engaged by it may be turned through a complete and repeated circle of rotative movement.

In order that the lever C may have an extended grip contact with the head a rounding toothed edge may be formed in the lever, or better, as shown, the lever where it engages the head is bent around the same. Attention is also directed to the fact that the rounding serrated edge of the lever where it engages the head is made longer than the nut receiving opening orjslot formed in the side of the head so that when the head has been turned to a position where the slot in the head will be adjacent to the engaging or toothed. portion of the lever there will still be left enough teeth for said lever to engage the head on one or both sides of said opening to continue its operation. of turning. In other words, the rounding toothed or serrated portion of the lever where it engages the head should be long enough to span the slot or opening in the head. Attention is also directed to the fact that the edge or side ortion b3 of the casing which lies back of the ever acts as a stop and prevents the lever from being thrown too far away from the head as well as assisting by the lever coneA tacting therewith in turning the casing on the hubs of the head in order that the lever may be thrown around to a position where it may obtain a fresh grip on the head as before described.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States 1. In a wrench, the combination of a rotatable head having a slot therein open from ths side of the head whereby it may be ap plied laterally to a nut or other object to be turned, bearings in which said head is mounted to turn rotatably and through a complete circle of rotative movement, said bearings being located in an annular plane outside the area traversed by the slot in said head as said head is turned through a complete circle of movement, and means for turning said head.

2. In a wrench, the combination of a rotatable head having a slot therein open from the side of the head whereby it may be a plied laterally to a nut or other object to lie turned, a head support having formed therein bearings in which said head is mounted to turn rotatably and through a complete circle of rotative movement, and means for turning said head, the same comprising a handle or lever pivotally connecting with said support and extending in part alongside or by said head whereby upon turning said lever in one direction it may engage with or grip said head and said head be turned by said lever or handle, or b turning said lever or handle in the reverse irection it may be turned away from contact or engagement with said head and become shifted to a position where it may make renewed contact or engagement therewith7 whereupon said head may be turned through one or more complete circles of rotative movement.

3. In a Wrench, the combination of a rotatable head having a slot therein open from the side of the head whereb it may be applied laterally to a nut or ot 1er object to be turned, said head also having hubs extending from the sides thereof, bearings for said hubs in which said head may turn through a complete circle of rotative movement, said bearings also beingl located in a plane outside the area traverse by the slot in said head as said head is turned through a complete circle of movement, and means for turning said head.

4. In a wrench, the combination of a rotatable head having a slot therein open from the side of the head whereby it may be applied laterally to a nut or other object to he turned, a casing in which said head is mounted to turn by bearings formed in the sides of said casing and in which bearings said head turns by hubs extending therefrom and through a complete circle of rotative movement, said casing also being open on the side thereof whereby the nut or object to be turned may enter the slot insaid head when the head is ap )lied to said nut, and means for turning sal head, the same comprising a handle or lever pivoted between the sides of said casing and ada ited to intermittently engage with said hea 5. In a wrench, the combination oia rota table head having a slot therein open -from the side of the head whereby it may be applied laterally to a nut or other object to )e turned, means for supporting said head whereby it may be turned through a complete circle oi rotative movement, a handle or lever pivotally supported and arranged and adapted in art to engage said head and when said head ias been turned to a cert-ain position to span the slot or opening therein and engage said head on one or both sides of said slot or opening.

6. In a wrench, the combination of a rotatable head having a slot therein open from the side of the head whereby it may be applied laterally to a nut or other object to be turned, a casing in which said head is mounted to turn by bearings formed in the sides of said casing and in which bearings said head turns by hubs extending therefrom and through a complete circle of rotative move ment, said casing also being open on the side thereof whereby the nut or ob`ect to be turned may enter the slot in said liead when the head is applied to said nut, and means for turning said head, the same comprising a handle or lever pivoted between the sides of said casing and adapted to intermittently engage with said head, said handle or lever at the point of its engagement with said head being adapted whereby it may span the slot or o ening in said head and engage with said hear on one or both sides of said opening when said head has been turned to a certain position, and a stop with which said handle or lever engages when turned away from.

said head.
